ZNET does a article on the Amazon / Soney question.

The report below asks for yhou to registerto get the full report;

The jest of it is taht the Q3 attackswere somewhat worse tahn earlier of  this year.

Compared to Q2 2014

    2 percent increase in total DDoS attacks
    80 percent increase in average attack bandwidth
    10 percent increase in average peak packets per second
    2 percent increase in application layer attacks
    2 percent increase in infrastructure layer attacks
    29 percent increase in average attack duration
    11 percent increase in multi-vector attacks
    183 percent increase in high bandwidth (100+ Gbps) attacks: 17 vs. 6

So, if you notice you are having frequent lost connections, it might not be your equipment.

If your favorite web site is not available, you might check with other users. Or look on sites like Twitter and Facebook to see if the sites administrators are reporting problems from some kind of DOS or DNS attacks.
Example: GMX, a popular e-mail site, reports they have some kind of problems.

Only web server issues I have seen have been just with the Blizzard gaming servers having issues. They were targeted with a massive DoS attack at the launch of the latest WoD expansion, as well as on top of that they have been consolidating blades to take on the role of multiple prior blades as their membership of customers dwindled following Cataclysm expansion onwards, and instead of having so many blades that were dedicated to realms that were low population in which the blades have excessive CPU idle time, they decided to merge multiple realms that otherwise use to be on dedicated blades to now where each blade was handling as many as 6 realms for the low population realms. They also implemented a cross realm merger which was to pool together people from multiple realms of diminishing subscribers as a means to try to generate more social interaction with other random players. This was a good change for realms that were dead because it meant that you now would cross paths with others in game who may not be on the same realm as you, but you could communicate and assist each other etc. I have heard rumors that with the WoD expansion Blizzard was not prepared to handle the inrush of millions of players coming back to the game and so while there was a DoS attack, I kind of wonder if it was a good reason to take advantage of to put the blame onto the DoS attackers when their infrastructure now being so consolidated now was overloaded because under the model of x-many more millions of players now the blades cant keep up with all the activity. I bought game time for the game, but hearing from friends that they have 253 minute wait times in queue to get on and were number 2673 in queue and this happened for days, i decided to hold off. Today it has been better as for Blizzard likely load balanced better by lighting up some new blades to relieve the load in a server cluster config. But after being off the game for almost a month, I am actually not feeling the need to go back just yet and so my game time will remain unactivated until i feel the need to go back and play  :-\

This is the only servers I have seen issues at lately other than CH going down that one day  :P
